<P>PROBLEM TO BE SOLVED: To prevent a content from jetting with air out of a spout tube in removing an overcap. <P>SOLUTION: This spout container is provided with a squeeze bottle, an inner lid where an opening A is formed when a pull tab 2a is pulled up, a spout plug 3 which is joined with the inner lid through a hinge 4 and is formed with a spout tube 3b and an over cap 5 with an outer wall which fits with the bottle removably. The cap 5 is formed with a protrusion 5p hanging down from the back face of its outer wall and an annular bulge 5s is formed wholly on the periphery of the protrusion. When the bulge is mounted on the bottle, it is inserted in the spout tube and seals an inside channel 3r. The protrusion 5p is extended to keep the channel 3r in a sealed condition even after the fitting of the bulge 5s relative to the bottle is released by making the length L<SB POS="POST">1</SB>from the outer wall back face of the cap 5 to the contact point of the bulge 5s longer than the moving distance H required for releasing the fitting with the bottle in removing the cap 5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
